-r(iI.1 I1\ re-'Ann Gamma arracnmnngr FOR snwme-macnmns Beaver Falls, inthe county of Beaver and covered certain new anduseful Improvements in'Foldin and Guiding Attachmentsfor SeWing-Ma 'l1ines, of which the followtherein to the accompanying drawings. This invention has for its object to f pro-' thestrip will be folded into a tubular form and the form a-fiat seam on one side ofthe tubular work produced, the stitches not, passing through and through the, work, and therewhenthe tubular product is flattencdout.

In the manufacture of mens trousers it is holding belts." These loops have heretofore usually been made by hand from \folded strips of material-like that from which the trousers are made; and this invention has for itsobject to provide a sewing machine by which a tubular product may be formed lengths for use as loops for the purpose just referred to. The present invention adapts cation No. 533,882, filed Dec. 18, 1-909 to cii -rocating needles. I

In the accompanying drawings Figure 1 is a side elevation of a sewing machine embodying thepresent invention.- Fig. 2 is a plan view of the forward end of the workma'chines having'vertically and laterally revention applied thereto. Fig. 3 is an end view of the Work-plate of the machine, with thepresentinventimi applied thereto, looking from the left of Fig. 1., Fig. 4, is a detail view of the folding and guiding scroll. I

vertically in aThorizontally swinging frame -orgat e 15 connectedby a pitma'n lti'witha vibrating segment 17, operated from a cam Wlilch performs .one rotation to two rotations of the driving shaft of the machine and with which driving shaft the needle bar has the usual crank and pitman connection, so that the needle bar will descend alternately in two different planes, as .is-com- 'mon with overseaming sewing machines.

screws 20 by which the said arm is secured to a portionof the work-plate 12, with provision for a limited adjustment. The scroll 18 is provided beneath the needle-bar with a notch 21 into which-the needle can pass institching. Extending into the said folding and guiding scroll- 18. is an elastic tongue 22 around which the work is folded and which tongue is carried by an arm '23 preferably, adjustably secured to the work-plate by means of screws 21.

Slidingly mounted in suitable ways in the work-plate 12 is a block 25 in which is journalcd'a. short vertical shaft 26 provided at its upper end with a ratchet wheel 27, said shaft. having at its lower end a serrated feeding wheel 28 having a vertical feeding face which extends within the folding and guiding scroll 18 through, an opening'29 formed in the vertical, bac'- portion of said scroll opposite the notch 21. The sliding block 25 is pressed toward the folding and guiding scroll 18 by means ofa spri 30, so that the serrated feeding wheel 28 "will be yicldingly forced toward the elastic tongue,

being attached to a block 33 pivotally mounted'on the upper end of an arm 34. attached to the feed-operating rock-shaft 35 of the machine-so that as the said-shaftjisrocked by the usual feed-operating mechanism of the machine the pawl will be reciprocated back and forth for the purpose of imparting an. intermittent rotary moveme'iit to the ratchet wheel 27 and to the serrated'feed wheel 28 1 connected therewith.

tongue extending into said scroll and-around 1 37. The sliding block 25' isprovided with Vertically pivoted to the work-plate 1 2 a cam bloc 36 provided with a hand lever.

a projection 38 in which is-tapped a screw 39 engagin the-cam block: 36, so that by turning sai hand blockby'means of'its cam lever-the sliding. block- 25 may be. retracted or forced away from the folding and guiding scroll'18 whenit is desired to remove or insert the work.

"In the operation of this machine the strip a which is to be stitched into tubular formwill be drawn into the folding and guiding I Y scroll 18 and said strip. will preferably be of such width that the edges thereof will overlap each other on the right hand side 1 of the elastic tongue, around which the said strip will be folded as'it-is drawn forward into the said folding and guiding scroll. For the convenient'insertion' of the work in this manner the bedplate is recessed or cut away in front at 40; When the work has thus been placed in'po sition and the machine i's-started the strip will be fed forward through the folding and guiding scroll l8 and the oierla'pping'edges ofthe strip will be overstitched, due to the alternate descent ofthe needle into and outside (to the right) of said-overlapping edges,- the "work being fed forward as the stitching progresses; thereby forming a tubular productjwhich -is 'stitehed together at one side, so that the stitches will not show on the fair side of said tubular product. The elastic tongue 22 stands upxe'dgewise vertically,- so that the tubular work-formed from the folded strip will be wider vertically than horizontally, and will be blind-stitched on the side thereof toward the feeding wheel28, the needle in its depth stitch descentspassing through the work on the right hand side (Figs. land 2) of the said elastic tongue.

The elastic tongue 22 receives the preselastic tongue 22 consists preferablyfof a sure of the feeding-wheel 28 induced bythe spring 30, andthis pressure may beregu: lated by adjustment of the screw 39 which thus serves as an adjustable stop acting against the cam block 36, to vary the working position of the sliding block 25 and the feeding wheel supported thereby. The said thin flat body arranged edgewise vertically,

as above stated,'and the feeding wheel or device has a vertical feeding face arranged opposite a portion of said tongue and pressed toward the latter by the spring 30.

Havin thus described my invention I claim and desire to secure by Letters Patent:
